Move html styles to common

Move all styles of HTML to common lib. Modify replacing in HtmlHelpService to use global match in order to replace all strings in the html. Replace HTML_HELPERS_DIR from StaticConfig with HTML_COMMON_HELPERS_DIR and HTML_CLI_HELPERS_DIR. The idea is to have specific helpers for each CLI and common helpers.
Add favicon and logo to docs/helpers dir.
